Now and then, the image from each eye is so different from the other that it seems the brain has trouble combining them into a coherent image. You can create this situation by putting a hand or sheet ...

I have a hypothesis that humans are better able to identify the largest (or smallest) in a set of objects, compared to their ability to identify an average object, i.e. the one closest to the mean.
...

I have read in some websites that the percentage of the cortex devoted to processing visual information is from 30-66% with some claiming even 90%. And compared to that, only about 3% is dedicated to ...

Gestalt Psychology maintains that we perceive a whole from parts, and that we fill in missing gaps. The "whole" we perceive is more than the sum of parts we perceive - it also involves what our minds ...

A person with schizophrenia sees a door become open, while in reality it's closed. What would he see when he tries to pass through the door?
Bumps into an invisible obstacle.
He sees the door become ...

I'm planning an event-related fMRI-experiment to investigate the difference in processing natural and computer-generated expressions. For this, we recorded videos of 4 different actors posing fearful ...

It's well known that mental imagery shares the neural substrates of its respective modality, despite dissociable multivariate patterns. For example, visual imagery can be decoded across the ventral ...

Most of the sources studying retina seem to suggest that retinal connectome is hardwired and species dependent (like specialized vertical movement detector in small rodents). I couldn't find a single ...

I know this is a basic question, but I can't find the answer anywhere. How can a cell that is not photoreceptive (eg LGN and retinal gangion cells) have a receptive field that is stimulated by "light" ...

I am looking for a "random-dot kinematograms" implementation in javascript/HTML that I can use in web-based experiments. Something like this, where the user can specify the direction using a mouse or ...

When things move really fast, you might notice that it looks broken down into discrete images at a fast enough speed, even though the object isn't actually teleporting. Or, in the case of staring at a ...

Firstly, I need to declare that I am not psychologyst, however I am currently working on visual recognition research. To be precise, I working on face recognition deficits in Autism Spectrum Disorder. ...

I am working on an animation in which there are three somewhat small font words (Environmental, Social, and Economic) together with three colored horizontal histogram bars on each side of the labels ...

I know that human vision can get accustomed to reverse vision when wearing reverse glasses for several days. But does it work when we see the reverse image just in certain moments throughout the day? ...

I have like 0 experience or knowledge about brain signals and all that stuff but I'm curious about how much we know about the brain in terms of like tricking your brain that with simulation of pain. ...

I am quite inspired by the results obtained by PredNet, which implements a predictive coding model using artificial neural networks. They compute the prediction error as a simple subtraction, and then ...

Sometimes, when you close your eyes in the dark, you see what looks like sparks or flashes. Sometimes when you are tired, your vision seems to shift sideways and realign, like someone bumped into a ...

I have asked the same question half a year ago on Graphic Design but received no useful answer.
According to the W3C (and another question on this site), the contrast ratio between body text and text ...

After understanding that cats cannot experience the Kiki/Bouba effect, I wonder if smart non-human primates can experience it. There is evidence suggesting that Chimpanzees associate high pitch with ...

I have done several searches without finding any papers addressing this question..
I'd like to know if there is any evidence to suggest that the strength of the simultaneous contrast illusion (or any ...

I was fascinated when I first read Ramachandran's article about kiki bouba effect, and I was wondering if cats experience the same thing... As Ramachandran proved, our angular gyrus is responsible for ...

Generally, people looking at an example of a Rubin Vase see either the vase, or the faces. The brain seems to make a decision on which one is being viewed, but both cannot be focused-on at the same ...

Im a painter for many years. When I paint, I usually walk around and look at my painting for many hours. When painting session is long, it harder and harder to maintain a "fresh look".
By fresh look; ...

Adobe Illustrator has taken over five minutes (and counting) to render a vector 2D image rotated 18° in 3D on my computer. And yet, I and nearly anyone else can easily visualize the subject rotated ...
